Abstract
It is shown that every non-periodic ergodic system has two topologically weakly mixing, fully supported models: one is non-minimal but has a dense set of minimal points, and the other one is proximal. Also, for a given Kakutani–Rokhlin tower with relatively prime column heights, it is demonstrated how to get a new tall Kakutani–Rokhlin tower with the same property, which can be used in Weiss’s proof of Jewett–Krieger’s theorem and in the proofs of our theorems. Applications of the results are given.
